December: Summer Delight, a Lot Less Heavy
December brings the official start of summer with the smallest average swell of the year at 6-7ft (2.0m) and the shortest period at 10.7s. But the surf remains consistent: SSW (29.1%), SW (18.1%) and S (14.6%) keep every day at least waist-to-head high, while the E/SE seas contribute another 18.3% of mixed energy. No N-ENE swell is on the charts, as usual.
The best news is wind. Ideal surfing time jumps to 29%, the highest of the year. SSW (6.7%), SW (12.6%) and WSW (15.6%) provide frequent offshore windows, while ENE/E/ESE are the trades to work around. Water temp 19.6°C, air temp 20.8°C; for clean, friendly December surf, this is about as good as Denvils gets.
